My bigger concern are those that have very poor social skills who bury themselves in online activities and never force themselves to interact face to face with others in order to develop those skills. They consequently lack the experience, pleasure and joy of "real" relationships.
Or maybe they simply don't enjoy relationships with most people. One thing I resented as a child were teachers coercing me to join activities with other children which I just didn't enjoy. Even worse, I picked up on the fact that they considered something wrong with anyone who didn't want to do the things "normal" children do. The labels given to those who didn't fit the mold, such as "shy" or "weird", are merely another way to force conformity. Sometimes they made the situation even worse by trying to force a friendship between me and other loners in class. More often than not, these others were the class losers who nobody wanted to bother with, so any association with them, forced or otherwise, further hurt my chances of making other friends. Even today I resent it when an adult will act as if there's something wrong with me, or my life is somehow empty, because I don't spend all my free time on the phone or going out with friends like many so-called normal people do. Like I said, too much human contact just smothers me. I've had friendships end because the people insisted on calling me every single day, often at length, to talk about nothing. They just didn't get it that I didn't enjoy this kind of regular contact. Oddly enough, the friends I've had who were more like me tended not to do things like this.
What it comes down to is that everyone is different. I wish society was more accepting of these differences. The long term damage done by the stigma associated with the labels given me by my teachers has probably hindered any socializing I might have done more than helped. The minute a kid is made to feel different, their self-esteem falls right though the floor. They may have meant well, but we all know the road to hell is paved with good intentions.
I definitely believe that many of them are grossly over diagnosed (and under diagnosed) and that far too many use them as excuses for lack of personal responsibility and accountability. But there are others who are severe enough to have their lives turned upside by them and that shouldn't be discounted or ignored.
That's really the problem. There is undoubtedly a condition called ADHD. Maybe 1 out of every 10000 children has a severe enough case that they need drugs to cope. This is a far cry from the 2 or 3 or 5 kids in every class who are diagnosed with this disorder. The majority of ADHD cases are simply healthy, normal children whom the caretakers don't want to deal with. It's easier to give a label and drug them into a stupor. Additionally, I think diet and lack of exercise are both to blame. Foods high in sugar make kids hyper. Lack of exercise due to many parents opting their children out of gym results in pent-up youthful energy with no place to go. The situation is undoubtedly the same with many other "disorders".
The question which begs asking is why do we want everyone to be exactly alike? This is even more curious since this is supposedly a society wihch embraces diversity. We should all learn to live with, respect, and love our differences. Without them, we would just be machines off an assembly line.
